#FUNFACT: Marine protected areas can help marine life rebound, protect at-risk species, and support our coastal communities.

As many countries work to expand ocean protections, hope for a thriving ocean grows.

Take two breaths… did you do it? 👀

Now thank the ocean, because it produces half the oxygen you breathe – all day, every day!

🌏 It also absorbs heat and CO2 from the atmosphere. Really, it’s working round the clock to keep our climate in balance.

But our ocean is in trouble. Since the 1970s, populations of oceanic sharks and rays have plummeted by over 70%.

It’s vital we reduce the pressure from overfishing and climate change, protect habitats and reduce plastic pollution 💙Share this post to give our ocean a voice!

[Erin Spencer, PhD @etspencer]

The final chapter of my PhD is published in @J_Exp_Biol. I’m proud of this work & excited to share it!

We used biologgers to estimate great hammerheads' temperature “sweet spot.” We saw they can perform well at a range of temps, which supports observations from the field. (1/2)

We reeled in some fun in our marine sanctuaries in 2025! 🎣

@marinesanctuary, in partnership with @NOAAFisheries, @NatParkTrust & other partners, hosted 5 free fishing clinics where over 100 families got out on the water for a day of fishing & fun! https://t.co/KTjRidHu1J

Ok, this is just cool! A new video from @Hihumpbackwhale raises public awareness about marine mammal entanglement while honoring the deep cultural and ecological connection Native Hawaiians hold with these migratory giants.

#DidYouKnow that manatees are the only herbivorous marine mammal?

@FloridaKeysNMS, which protects one of the world’s largest contiguous seagrass habitats, is the perfect place for manatees to munch on 150 pounds of plants daily! https://t.co/E0AMD1BYGi #ManateeAppreciationDay
